Me (M20) and my girlfriend (F19) liking different porn - with a twist!

For a few years now I’ve been questioning my sexuality and testing myself to see what turns me on, turns out i have a few kinks that i haven’t (publicly) shared to my GF, we’re almost 2 years into our relationship and the longer we’ve been together the more I’ve secretly performed these kinks for example, chastity, sounding, cuckolding role-play (too scared to have the real thing) and sissy related activities, anal and SPH as well as size comparison.

The other day were were about to have sex and decided to watch porn together on her reddit, she was watching rough porn and kept saying, “i’d love you to fuck me like this” and “please use me like these sluts” i was touching myself with her and was responding saying i would and the average sexual talk like “I’m gonna make you unable to walk” etc etc, but if got to a video 2 on screen the top was a girl in doggy that she was looking at, and the bottom was a woman being violently fucked by multiple men. I’m not talking about normal fucking, they were ruining the woman!

She was invested in the doggy, moaning and finger fucking herself begging me to fuck her in doggy like her, i was instead imagining myself getting destroyed multiple big strong men being passed around like a cheap fuck, she got close and just as the men came in the video all over this woman (who i was imagining was me) i came uncontrollably!

I felt like i was orbiting the sun, my GF came as well just before i did but it meant we couldn’t fuck until later, it felt amazing though, and the best part is that she doesn’t have a clue, she thinks i came from seeing her cum which i’m fine with her thinking but the memory and the feeling were so intense and amazing, I’ll probably try and get her to do it again.
